It seems that in the US people have been more obsessed with spelling things with their phone numbers. A practice likely tied to a time when television advertisements and phone numbers needed to be remembered to be effective. I find that I ignore almost all phone calls from numbers I don't recognized due to the prevalence of telemarketers, so I can imagine how this sort of hierarchy of numbers might appeal to certain people.
